Abstract
We study the classical collisions of electrons with one-electron atoms or ions in a model where both electrons are restricted to spherical states. At negative total energy, we calculate the probability for bound motion of both electrons occurring—as opposed to undelayed direct or exchange scattering. At positive total energy, we calculate the probability for (e,2e) reactions. There is a finite threshold for the onset of (e,2e) reactions. Its value depends on the nuclear charge and can be deduced from a simple transcendental equation. The general behavior of the probability for (e,2e) reactions as a function of energy is quite similar to the results of quantum-mechanical calculations and to experimental data.Keywords
